Voltage Support Capacity Improvement for Wind Farms with Reactive Power Substitution Control

CSEE Journal of Power and Energy Systems
Generally, voltage support at the point of common coupling (PCC) of a wind farm is achieved through centralized static var generators (SVGs). Since the reactive power requirements occupy their capacity in a steady state, the reactive power support ...

Review of low voltage ride‐through technology of doubly‐fed induction generator

The Journal of Engineering, 2018
In recent years, with the increasing of wind power development, the demand for low voltage ride‐through (LVRT) technology was proposed to ensure the safe and reliable operation of the power system. The key issue of LVRT strategy for doubly‐fed induction generator (DFIG) varies according to the network synchronisation modes.

Low-Voltage Ride-Through Algorithm for Grid-Forming Converters

IEEE Transactions on Power Electronics
In recent years, the increasing integration of renewable energy sources into power systems has led to significant changes in grid operation. Power electronic converters are primarily used to connect these power plants to the electrical system and, as key components in modern power systems, grid-forming (GFM) converters have emerged to provide the ...

An Adaptive Series-Dynamic-Resistor-Based Protection Scheme for Brushless Doubly- Fed Induction Generator Under Asymmetrical Fault Conditions

IEEE Access
Low-voltage ride-through (LVRT) is one of the most important criteria for integrating wind energy into the power grid. Based on grid connection codes, wind generators must remain connected during fault conditions.

A DFIG low- and High-Voltage cascading failure through strategy based on GSC and RSC joint control

International Journal of Electrical Power & Energy Systems
In wind power DC transmission systems, commutation failures cause significant reactive power fluctuations at the direct current (DC) transmission end, leading to sequential changes in voltage from low to high and often causing wind turbines to disconnect

Enhanced Control Strategies for Improving Low Fault Ride-Through Capability of Grid-Connected Doubly Fed Induction Wind Turbines

Energies
The DFIG faces challenges in providing fast and accurate support during grid voltage fluctuations. Severe voltage dips can trigger peak currents, which may damage the converter equipment and even lead to the disconnection of turbines from the grid.
